I’ve been reading The Forgotten Man: A New History of the Great Depression by Amity Shlaes [Kindle, Sony, Kobo], and there was then-Secretary of the Treasury Andrew Mellon in his book Taxation: The People’s Business, citing a lesson print publishing still refuses to heed in regard to eBook pricing:

Does anyone question that Mr. Ford has made more money by reducing the price of his car and increasing his sales than he would have made by maintaining a high price and a greater profit per car, but selling less cars?

Boldfaced emphasis added by me.

Interesting how eBook device prices have plummeted to less than half of what they used to be, yet print publishing conspires to fix eBook prices to be high!
